Crystal Palace are hoping for a cash boost from Tottenham.
The Mail on Sunday says Palace want Tottenham to ease their financial crisis by renegotiating the transfer deal for Bostock.
The club are in administration with debts of more than £30million and need to raise around £4m to stay in business until the end of the season.
The sale of striker Victor Moses should bring in more than half of that after he was permitted to speak to a Premier League club - thought to be Wigan.
But that would still leave them short and administrator Brendan Guilfoyle has tried to reopen the deal which prompted chairman Simon Jordan to try to sell Palace.
Bostock, 18, joined Spurs in the summer of 2008 amid acrimony as a tribunal set the initial fee at £700,000.
Jordan described the amount for the talented midfielder as the football equivalent of 'a packet of crisps'.
But it could rise to £1.25m depending on Bostock's success and Guilfoyle hopes Tottenham will be willing to settle the deal with a final payment now.
